I just purchased a wonderful YB 400 International; great radio
for the price.
I tried to use a wall-cube PS (stabilized, well filtered) but
I get strong interferences on some SW band caused by it; with batteries
all is fine.
The noise may not be from your power supply, if can be from a source in
your
house (or nearby house) and be conducted through your power line, then
power
supply, then to your receiver. Before you invest too much in a new power
supply, try to eliminate the power lines as a source. Radio Shack has many
power supplies and they have a pretty good return policy. Purchase one
from
them, connect it and see if there is a difference. If the noise is the
same
then it is coming from someplace else through your power lines.
